dc.description.abstractEnPlanting is a widespread propagation technique for woody plants. Container-growth and plantation is likely to heavily alter root architecture and thus modify anchorage. The Landes forest is located South-West France and produces 20% of french wood, it is mainly composed of intensively managed even-aged stands of P. pinaster (Ait). Most reforestation is made by planting genetically improved varieties, from seeded nursery stock. Soils are entic to albic spodosols which are acidic, sandy, and lenses of cemented spodic horizon can occur. Root system architecture is a key component in mechanical stability of trees. In their first 15 years, pines are mainly anchored by a rigid vertical and deep taproot (Danquechin Dorval 2016). Older trees are anchored by a rigid cage mainly composed of regularly spaced strong shallow roots from which branch secondary sinkers (Danjon et al. 2005). The main framework of the central part of the root system is established at 4-years-old with a clear identification of root types (Saint Cast et al. 2020). In this study, we characterize the deformations of root systems of P. pinaster saplings grown in containers and planted in the field. Incidence on root system architecture is analysed.
